• Openings with 3m of the northern and southern boundaries require protection in accordance with Clause C3.4 of BCA or via an alternative solution

• Travel distances to a required exit or a point of choice between exits does not comply with BCA Clauses D1.4.

• The location of the fire booster assembly unit requires protection as per E1.3 of BCA and AS 2419.1 2005.

• The development will require a sprinkler system to the basement carpark levels complying with Spec E1.5 of the BCA and AS2118.1- 1999.

• The development is subject to requirements contained within Part D3 of the BCA, AS 1428.1-2009 and the Premises Standards. It is recommended that a separate report from a suitable qualified access consultant would be suggested to demonstrate compliance with all mentioned applicable provisions

20


CONCLUSION It is the opinion of this office that, on satisfaction of the above recommendation, the proposed building is capable of achieving compliance with the requirements of the Building Code of Australia (BCA) 2015 Volume 1, and relevant adopted standards without undue modification to the design or appearance of the building. Whilst the above recommendation have been made as a means of achieving compliance with the various provisions of BCA Performance Requirements their acceptability has not been verified at this time. It will be necessary for the design to be reviewed by an appropriately qualified person prior to the issue of a Construction Certificate for the works.
